Summer at competition level?
The problems with traditional summer hats.
When the sun is beating down, any hat becomes a heat trap. Without active cooling technology, heat builds up and sweat runs unchecked – your performance drops with every passing minute.
Heat build-up
With traditional summer caps, heat builds up beneath the fabric. Your head overheats, your performance plummets – just when you need it most.
Sweat on your face
Without active sweat-wicking, moisture runs unchecked into your eyes and down your neck. Instead of evaporating, it sticks to your skin and disrupts your rhythm.
Unprotected from the sun
Without sun protection, you run the risk of getting burnt in direct sunlight. Heatstroke, sunburn and the risk of skin cancer are the consequences.
Heavy & cumbersome
Summer caps made from thick cotton soak up sweat, become heavy and chafe. You just want to take it off and expose yourself to the sun.

Frequently asked questions.
The most important answers about the Strato Cooling range.
What is brrr° Triple-Chill technology?
brrr° is an innovative and patented cooling technology for textiles designed for high-performance use, even in very warm temperatures. The combination of three cooling effects achieves an immediate and lasting reduction in temperature: naturally cooling minerals, active moisture wicking and rapid drying draw heat and moisture away from the skin. This keeps your head cooler whilst exercising – even in very warm temperatures.
Which Strato models are available?
The Strato range comprises four styles, all featuring the same brrr° cooling technology:
Strato Cap (€44.99) – the classic style with a minimalist, sporty design

Strato Cap with sun protection (€54.99) – with integrated neck protection
Strato Bucket Hat (€59.99) – with a 360° brim for maximum UV protection
Which sports is Strato designed for?
Strato is the performance range for the warmer months – so running, trail running, hiking, multisport, ski touring on warm days and outdoor activities in high temperatures. The brrr° Triple-Chill technology comes into its own wherever heat and sweat become a burden.
What sizes and colours are available?
All Strato models are designed as one-size-fits-all unisex styles. The highly elastic functional fabric moulds to the head and sits securely without digging in. Each model is available in three colours: Earth Brown, Black and White.
How should Strato be cared for?
Gently hand wash at 30 °C in cold water. Do not use fabric softener or tumble dry – otherwise the brrr° functional fibre will be damaged. The cooling minerals are woven directly into the yarn and remain effective even after hundreds of washes.
